What is wrong with my computer power button?

Each time i use my computer, it seems harder for me to press the power button to make it turn on. My computer is perfectly fine but my power button can’t seem to switch it on. Its not that its hard to press, but its hard to get it on even if u press the button all the way. I’m scared i will never be able to turn my computer on if this keeps on.

there should be some problem at the power button or power switch which placed on mother board see that all power switshes are placed correctly
